      ** Confidential treatment requested
<PAGE>
any claim of any of the EPSON Licensed Patents" as used in the previous sentence
shall be interpreted to include, but not be limited to: (1) "TransAct Licensed
Products" wherein the product offered to a customer includes the option to
utilize EPSON Licensed Patents ESC/POS Function and/or Command, if such
utilization would result in infringement; (2) TransAct Licensed Products wherein
software is supplied to the customer including EPSON Licensed Patents ESC/POS
Function and/or Command, if such software would result in infringement; or (3)
TransAct Licensed Products wherein the customer may select EPSON Licensed
Patents ESC/POS Function and/or Command from a series of offered commands, if
such selection would result in infringement. Such payments shall be due and
payable upon the first invoicing or shipment by any TransAct entity. Each
TransAct Licensed Product shall be considered "sold" under this Agreement when
billed to the purchaser, or if not billed, then when shipped; or when paid for,
if paid for by the purchaser before shipment. TransAct shall pay such royalties
to EPSON on a quarterly basis, i.e. on each period ending March 31st, June 30th,
September 30th and December 31st. Each payment shall be made within thirty (30)
days of the end of each quarter. For calendar year 2003, all royalties shall be
paid no later than thirty (30) days after the last Party executes this
Agreement, and shall cover the period from January 1, 2003 to December 31, 2003.
No royalties shall be due for TransAct's sale of printers to any third party
that is already obligated to pay EPSON royalties relating to the sale or use of
TransAct Licensed Products. In the event of a return of a sold product for which
a royalty has been paid or is due, and a substitute or replacement product is
provided in exchange for the sold product (e.g., warranty return and exchange),
no additional royalty shall be due for the substitute or replacement product
provided in exchange. In addition, TransAct shall be entitled, with respect to
any product sold for which royalties have been paid or are due, to a credit for
such royalties in the event the product is returned to TransAct and no
royalty-bearing product is provided in exchange for such returned product.

      5.03 Non-refundability. All payments made under this Agreement are
non-refundable, except to the extent of any adjustments for payment calculation
errors or product returns.
